LRGB HA Newtonian image of NGC2903 and dwarf satellite UGC 5086

NGC 2903 is a barred spiral galaxy 100,000 light years in diameter, located in Leo , is a member of the Virgo supercluster and is about 30M light years distant. It is undergoing a rapid phase of star formation near the barred core with plenty of HA detectable near the galaxy centre. An irregular dwarf galaxy UGC 5086 visible to the side shows similar motion and is thought to be a satellite galaxy (Z =0.00172 compared to 0.00185 for NGC2903) about 2 M ly distant from NGC2903.

Here about 2h of luminance data --imaged at resolution about FWHM 2.4 - was added to about 3h of RGB data with some HA added into the red channel. Images all captured in Sharpcap and processed in PixInsight. Data for the final image accumulated over two years under rather poor Bortle 7 skies.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
